Cerebral infarction is divided into 2 cases for interventional treatment: 1, ultra-early, if ultra-early interventional treatment is done, the earlier the better the time is for sure. Ultra-early treatment, whether intravenous thrombolysis, or arterial retrieval of embolism, the earlier the better, must be a race against time, can not be delayed until the time window for treatment, the earlier the better, the earlier the patient stroke damage is smaller; 2, for elective surgery, ischemic cerebrovascular disease caused by large vessel stenosis intervention, such as patients with TRA, small stroke, to do interventional treatment. If the patient has very mild symptoms, transient cerebrovascular attack, transient ischemic attack, or a very small stroke, treatment can be done within 2 weeks of onset. In patients with a relatively large infarct area, interventional treatment should be done with caution because treatment at an early stage is prone to a hyperperfusion reaction, causing severe edema in the patient and resulting in bleeding. Treatment in this case is usually performed after 3 weeks, which is relatively safe. The earlier the interventional treatment for cerebral infarction is super early, the better. For elective surgery, patients with mild symptoms can be treated within 2 weeks, and if the infarct area is relatively large, treatment after 3 weeks is recommended.
